Well, now everyone who works on the Internet and at least somehow connected with cryptocurrencies is happy to accept payment in eth and BTC. I personally prefer to get paid in ethereum
Yes, if there is a relationship with crypto, then the cryptocurrency serves as a means of payment. Many resources still use conventional electronic money, such as PayPal, Skrill, and others. For cryptography to conquer the world still has a long way to go.
I suggest two types of developments. Either cryptocurrencies in general will cease to be interesting, or they will begin to be massively introduced into the economy. I think the second option is more likely.
